Erase SAMSUNG T3 ssd external bootcamp but failed

[gpwz-zhen]

Hi guys,

I got this samsung t3 ssd for an external bootcamp, then I decided to erase it since I am now using Parallel virtual more often, I tried to use Disk Utility to erase it and it was failed, now I am stuck...

Here's what it looks like right now (attached screen shot)... totally beyond my intelligence... anyone could help? thanks!

Open Disk Utility.
Click the View icon, and choose "Show All Devices"
Now, select the line with the external drive information, such as the model number for your Samsung T3.
NOW, click Erase. You can name the partition whatever you like (if you don't like "Unnamed", etc )
Click Erase to continue with the reformat. Should only take a few seconds to complete
and ... Done.

thank you~ it's more complicated than this... i believe it's the problem from the disk2s2 (Apple_HFS >16EB), i tried to delete this volume and always give me an error (disk2s2 is neither an APFS Container Reference nor an APFS Physical Store)...

Now it looks like this... how could I get rid of this disk2s2...
